Claude Code Tip#02: Planning Mode vs Thinking Mode

Claude has two modes for handling complex tasks , Planning Mode and Thinking Mode.

Planning Mode = Breadth : looks wide across your whole project

Thinking Mode = Depth : thinks hard about one specific problem

---

Planning Mode

Think of it like a contractor who walks through your entire house before starting any work. They check every room, understand what is connected to what, and make a list before picking up a single tool.

Use it when a task touches multiple parts of your project. For example: “Add a login feature.” That affects the database, the backend, the frontend, and maybe tests. Planning Mode makes Claude map it all out first before writing a single line.

Thinking Mode

Think of it like a doctor who sits down, studies your test results carefully, and works through the diagnosis step by step , rather than giving a quick answer.

Use it when you have one hard problem to crack. For example: “This calculation gives the wrong result for large numbers , why?” That is not a wide problem, it is a deep one. Thinking Mode makes Claude slow down and reason through it properly.

We can use both modes together. If the task is both wide and hard , say, “refactor the whole payment flow and fix this tricky discount bug” , use both.

Just keep in mind: both modes use more tokens, so there is a cost. For simple tasks, neither is needed.
